RESUMEN
Purpose@#Preoperative identification of the intraosseous posterior superior alveolar artery (PSAA) is critical when planning sinus surgery. This study was conducted to determine the distance between the cementoenamel junction and the PSAA, as well as to identify factors influencing the detection of the PSAA on cone-beam computed tomography (CBCT). @*Materials and Methods@#In total, 254 CBCT scans of maxillary sinuses, acquired with 2 different scanners, were examined to identify the PSAA. The distance from the cementoenamel junction (CEJ) to the PSAA was recorded at each maxillary posterior tooth position. Binomial logistic regression and multiple linear regression were employed to evaluate the effects of scanner type, CBCT parameters, sex, and age on PSAA detection and CEJ-PSAA distance, respectively. P-values less than 0.05 were considered to indicate statistical significance. @*Results@#The mean CEJ-PSAA distances at the second molar, first molar, second premolar, and first premolar positions were 17.0±4.0 mm, 21.8±4.1 mm, 19.5±4.7 mm, and 19.9±4.9 mm for scanner 1, respectively, and 17.3±3.5 mm, 16.9±4.3 mm, 18.5±4.1 mm, and 18.4±4.3 mm for scanner 2. No independent variable significantly influenced PSAA detection. However, tooth position (b = - 0.67, P<0.05) and scanner type (b = - 1.3, P<0.05) were significant predictors of CEJ-PSAA distance. @*Conclusion@#CBCT-based estimates of CEJ-PSAA distance were comparable to those obtained in previous studies involving cadavers, CT, and CBCT. The type of CBCT scanner may slightly influence this measurement. No independent variable significantly impacted PSAA detection.
RESUMEN
Abstract Introduction Despite several pediatric tracheostomy decannulation protocols there remains tremendous variability in practice. The effect of tracheostomy capping on decannulation has been studied but the role of speaking valves (SVs) is unknown. Objective Given the positive benefits SVs have on rehabilitation, we hypothesized that SVs would decrease time to tracheostomy decannulation. The purpose of the present study was to evaluate this in a subset of patients with chronic lung disease of prematurity (CLD). Methods A retrospective chart review was performed at a tertiary care children's hospital. A total of 105 patients with tracheostomies and CLD were identified. Data collected included demographics, gestational age, congenital cardiac disease, airway surgeries, granulation tissue excisions, SV and capping trials, tracheitis episodes, and clinic visits. Statistics were performed with logistic and linear regression. Results A total of 75 patients were included. The mean gestational age was 27 weeks (standard deviation [SD] =3.6) and the average birthweight was 1.1 kg (SD = 0.6). The average age at tracheostomy was 122 days (SD = 63). A total of 70.7% of the patients underwent decannulation and the mean time to decannulation (TTD) was 37 months (SD = 19). A total of 77.3% of the patients had SVs. Those with an SV had a longer TTD compared to those without (52 versus 35 months; p = 0.008). Decannulation was increased by 2 months for every increase in the number of hospital presentations for tracheitis (p =0.011). Conclusion The present study is the first, to our knowledge, to assess the effect of SVs on tracheostomy decannulation in patients with CLD showing a longer TTD when SVs are used.
RESUMEN
Cajanus cajan is generally grown in rainfed condition. The crop is also a good annual host plant of lac insect. C. cajan is widely reported to have biotic stress due to insect pests on it. Lac insect is phloem sap feeder and hence imparts biotic stress. The present field study was conducted to evaluate the percent survival of lac insects on C. cajan by adjusting different levels of biotic and abiotic stress on the host plant. The biotic stress due to insect pests on C. cajan was minimised with periodic spray of contact insecticides. The varying level of biotic stress i.e., No, Low, Medium, and High level was maintained on C. cajan plants with lac insects on it. The three levels of abiotic stress in this experiment were considered in terms of soil moisture stress. It was managed through irrigation per plant through drip system, it was considered that creating different levels of moisture stress in soil will impact the host plant. The abiotic stress was of three levels i.e., Low, Medium, and High. The result reveals that survival percent of Lac insect from brood lac inoculation to the harvest of lac crop was highest 37.52 percent on C. cajan with one primary branch and its secondary branches with lac insect (L1- Low biotic stress). It was 32.13 percent (W3- Low soil moisture stress). The study indicates that biotic and abiotic stress play a major role in the survival of K. lacca.

RESUMEN
Background: There are different types of adhesives and resins available today for the treatment of dentinal hypersensitivity. Literature search showed fewer comparative studies using gluma desensitizing agent and diode laser (940nm) in the treatment of dentinal hypersensitivity. Hence, the aim of present study is to compare the efficacy of gluma desensitizing agent and diode laser (940 nm) in the treatment of dentinal hypersensitivity. Methods: Patients were selected using VAS scale and randomly divided into group 1 (gluma) and group 2 (diode laser). Gluma and laser treatment was done for the patients on the contralateral sides. The follow up was done at an interval of 1 month and 3 months. Results: Statistically significant difference was seen in intra group comparison for both gluma and laser treatment but no statistically significant difference was seen in the intergroup comparison of both the groups. Conclusions: Both gluma and diode laser treatment were found to be equally effective for the treatment of dentinal hypersensitivity.
RESUMEN
Background: To study the effect of blood alcohol levels on GCS in Traumatic brain injury patients (TBI) and relate the findings to brain injury severity based on the admission CT scan. Methods: This cross-sectional study with a comparison group is conducted in Emergency Department (ED) of Pushpagiri Institute of Medical Sciences and Research Centre, Central Travancore, Kerala, India from April 2016 to September 2017 including all patients of 18 - 70 years of age presenting with head injury. 200 participants, 100 each of alcohol intoxicated and non- intoxicated were selected by consecutive sampling. GCS, Blood alcohol concentration-BAC (derived from the reading of alcohol breath analyzer) and admission CT Rotterdam Score are collected and analyzed at the end of study. Results: When CT Rotterdam Score is 1-3, GCS was found to decrease with increase in BAC (Chi-square test p value=0.011; Spearman’s Rank Correlation coefficient rs=-0.326). Independent t –test showed that at BAC 1-100 mg/dl, mean GCS decrease by 1.6 while only same decrease is found when the BAC levels ranges from 100-400 mg/dl. When the CT Rotterdam score is 4-6, no significant correlation was found between GCS and BAC (p value=0.092; rs=0.214). In the presence of alcohol, GCS had sensitivity 87.5% and specificity 70% in comparison to alcohol absent TBI patients (sensitivity 98.5%, specificity 69.7%). When features of hypoxia and shock are present, GCS have good agreement with actual CT findings of TBI. (Kappa coefficient: K 0.659, sensitivity 76%, specificity 100% in alcoholics and K 0.756, sensitivity 100%, specificity 80.6% in nonalcoholic). Conclusions: Even in the setting of alcohol intoxicated TBI patient, Glasgow coma score is a useful tool for quick decision making in emergency department.

RESUMEN
Selfies are exploding social media all over the world. The number of self-portrait photos posted online has grown rapidly as a function of the simultaneous growth of social networking and smart phone use. It has triggered a number of risk taking and offensive public behaviour, pushing the boundaries of safety and decorum. Hence, the following study was undertaken to assess the prevalence of Selfitis in the upcoming generation of today's world, whose life mostly revolves around social media and friends. To assess the prevalence of Selfitis among undergraduate I year students. To associate the prevalence of Selfitis among undergraduate I year students with selected socio-demographic variables. Non-experimental univariate descriptive survey approach was used to determine the prevalence of Selfitis among undergraduate I year students of Arts and Commerce Colleges (n=200). Selection of the institution was done by non-probability convenient sampling technique and undergraduate I year students were selected by non-probability purposive sampling technique from Bhopal city, Madhya Pradesh. The modified Selfitis Behaviour Scale developed by Janarthanan Balakrishnan and Mark D. Griffiths was used for data collection. The findings revealed that the overall prevalence of Selfitis was 97.5% (195) and 2.5% (5) of individuals did not have Selfitis and prevalence of acute Selfitis was higher i.e. 76.92% (150) and that of chronic Selfitis and borderline Selfitis was 11.28% (22) and 11.8% (23) respectively. The mean and standard percentage of the score was 49.3850 and 15.05357 respectively. The prevalence of Selfitis was higher in males (52.82%) as compared to females (47.18%). Hence, it is evident that there is significant prevalence of Selfitis among undergraduate I year students. Except gender none of the socio-demographic variables influenced the prevalence of Selfitis. The craze of selfies is turning out to be very harmful for adolescents because it is at this age that identity of an individual develops and if these unreal standards of appearance are bombarded on the young mind, it will have a catastrophic effect on the whole generation.
RESUMEN
Objective To investigate vaccine hesitancy leading to underimmunization and a measles outbreak in Rwanda and to develop a conceptual, community-level model of behavioural factors. Methods Local immunization systems in two Rwandan communities (one recently experienced a measles outbreak) were explored using systems thinking, human-centred design and behavioural frameworks. Data were collected between 2018 and 2020 from: discussions with 11 vaccination service providers (i.e. hospital and health centre staff); interviews with 161 children's caregivers at health centres; and nine validation interviews with health centre staff. Factors influencing vaccine hesitancy were categorized using the 3Cs framework: confidence, complacency and convenience. A conceptual model of vaccine hesitancy mechanisms with feedback loops was developed. Findings: A comparison of service providers' and caregivers' perspectives in both rural and peri-urban settings showed that similar factors strengthened vaccine uptake: (i) high trust in vaccines and service providers based on personal relationships with health centre staff; (ii) the connecting role of community health workers; and (iii) a strong sense of community. Factors identified as increasing vaccine hesitancy (e.g. service accessibility and inadequate follow-up) differed between service providers and caregivers and between settings. The conceptual model could be used to explain drivers of the recent measles outbreak and to guide interventions designed to increase vaccine uptake. Conclusion :The application of behavioural frameworks and systems thinking revealed vaccine hesitancy mechanisms in Rwandan communities that demonstrate the interrelationship between immunization services and caregivers' vaccination behaviour. Confidence-building social structures and context-dependent challenges that affect vaccine uptake were also identified.
Objectif Déterminer si une intervention au niveau de l'eau, de l'assainissement et de l'hygiène pourrait avoir une influence sur les comportements en la matière, considérés comme importants dans la lutte contre le trachome. Méthodes Nous avons mené un essai randomisé par grappes dans les régions rurales d'Éthiopie entre le 9 novembre 2015 et le 5 mars 2019. Nous avons réparti aléatoirement 20 échantillons où l'intervention consistait à développer les infrastructures d'assainissement et d'approvisionnement en eau et à promouvoir l'hygiène, et 20 échantillons n'ayant fait l'objet d'aucune intervention. Tous les échantillons du groupe d'intervention ont suivi une formation sur l'hygiène à l'école primaire, disposaient d'un point d'eau communautaire, d'un poste de lavage par ménage, de savon à domicile, et recevaient des visites de la part de travailleurs chargés d'enseigner les bonnes pratiques en matière d'hygiène. Nous avons évalué le niveau d'observance des mesures en effectuant des enquêtes annuelles au sein des foyers. Résultats En l'espace de 3 ans, le nombre de postes de lavage, de savons et de latrines dans les ménages a davantage augmenté dans le groupe d'intervention que dans le groupe de contrôle: la différence de risque s'élevait à 47 points de pourcentage (intervalle de confiance de 95%, IC: 4153) pour les postes de lavage, à 18 points de pourcentage (IC de 95%: 1224) pour le savon et à 12 points de pourcentage (IC de 95%: 519) pour les latrines. La proportion de gens déclarant se laver le visage au savon était plus grande dans le groupe d'intervention (différence de risque de 21 points de pourcentage; IC de 95%: 1527 pour les enfants de 0 à 5 ans), tout comme celle mentionnant l'usage de latrines (différence de risque de 9 points de pourcentage; IC de 95%: 215 pour les enfants de 6 à 9 ans). Pour de multiples indicateurs, il a fallu attendre minimum un an après l'instauration du programme pour que les variations observées entre les groupes d'intervention et de contrôle deviennent statistiquement significatives; ces variations se sont ensuite maintenues lors des visites ultérieures. Conclusion Intervenir à l'école et au sein de la communauté a permis d'améliorer l'accès à l'hygiène et les comportements en la matière. Néanmoins, cette évolution prend du temps et plusieurs années d'intervention sont nécessaires.

Introducción: El conocimiento profundo de la anatomía microquirúrgica del lóbulo de la ínsula es crucial para operar pacientes con tumores en esta región. Objetivo: El objetivo de la segunda parte de este estudio es correlacionar la anatomía microquirúrgica con casos ilustrativos retirados de nuestra casuística de 35 pacientes en los cuales fueron realizados 44 cirugías de tumores en relación con el lóbulo de la ínsula. Material y Métodos: A lo largo de marzo de 2007 y agosto de 2014, 44 microcirugías fueron realizadas en 35 pacientes portadores de tumores insulares y los hallazgos de las cirugías y mapeo cerebral se correlacionaron con la anatomía microquirúrgica. Resultados: De una serie de 44 pacientes con tumores de la ínsula, la mayoría de los casos eran gliomas de bajo grado de malignidad (29 casos). El inicio de los síntomas en 34 pacientes fue epilepsia, siendo esta refractaria al tratamiento medicamentoso en 12 casos. El grado de resección fue subtotal o total en la mayoría de los casos de la serie. La mejoría en la calidad de vida (epilepsia, etc.) estuvo presente en más de la mitad de los pacientes. El déficit neurológico permanente estuvo presente en tres pacientes. Conclusión: En los tumores insulares, es tan importante el conocimiento profundo de la anatomía, como el saber utilizar e interpretar en tiempo real las observaciones de la monitorización neurofisiológica intraoperatoria.
Introduction: The deep knowledge of the microsurgical anatomy of the insular lobe is crucial to operate patients with tumors in this region. Objectives: Our purpose in this second part is to correlate insular surgical anatomy with illustrative cases from 4 surgeries performed on 35 patients with insular tumors. Materials and Methods: From March 2007 to August 2014, 44 microsurgeries were performed on 35 patients with insular glioma tumors. Of these, 29 cases were low-grade gliomas. Seizures were the first symptom in most cases. Total, or near total tumor resection was achieved in most of the patients. Improvement in quality of life was achieved in more than half of the patients after surgery. Moderate and permanent neurological deficits were present in 3 patients. Results: The majority of cases were low grade malignancy gliomas (29 cases). The onset of symptoms in 34 patients was epilepsy, being refractory to drug treatment in 12 cases. The degree of resection was subtotal or total in most cases of this series. The improvement in the quality of life (epilepsy, etc.) was present in more than half of the patients. Permanent neurological deficit was present in three patients. Conclusion: For insular tumors, microsurgical anatomy knowledge is as important as cortical and subcortical mapping

Introducción: El lóbulo de la ínsula, o ínsula, se encuentra oculto en la superficie lateral del cerebro. La ínsula está localizada profundamente en el surco lateral o cisura silviana, recubierta por los opérculos frontal, parietal y temporal. Objetivo: Estudiar la compleja anatomía del lóbulo de la ínsula, una de las regiones de mayor complejidad quirúrgica del cerebro humano, y su correlación anatómica con casos quirúrgicos. Material y Métodos: En la primera parte de este estudio presentamos los resultados de nuestras disecciones microquirúrgicas en fotografías 2 D y 3D; en la segunda parte de nuestro trabajo, la correlación anatómica con una serie de 44 cirugías en pacientes con tumores de la ínsula, principalmente gliomas, operados entre 2007 y 2014. Resultados: Extenso conjunto de fibras subcorticales, incluyendo el fascículo uncinado, fronto-occipital inferior y el fascículo arcuato, conectan la ínsula a las regiones vecinas. Varias estructuras anatómicas responsables por déficits neurológicos severos están íntimamente relacionadas con la cirugía de la ínsula, tales como lesiones de la arteria cerebral media, cápsula interna, áreas del lenguaje en el hemisferio dominante y arterias lenticuloestriadas. Conclusión: El entrenamiento en laboratorio de neuroanatomía, estudio de material impreso en 3D, el conocimiento sobre neurofisiología intra-operatoria y el uso de armamento neuroquirúrgico moderno son factores que influencian en los resultados quirúrgicos
Introduction: The insular lobe, or insula, is the cerebral lobe sitting deep in the sylvian fissure and hidden by the lateral surface of the brain. It is covered by the frontal, parietal and temporal operculum. Objectives: To study the anatomy of the insular lobe, one of the most complex parts of the human brain, and to correlate this anatomy with intraoperative findings. Materials and Methods: In the first part of this article we show the results of our dissections, documented in 2D and 3D, and focus on microsurgical anatomy. In the second part we correlate the anatomical structures with intraoperative findings from 44 insular tumor surgeries, mainly gliomas, of patients operated on from 2007 to 2014. Results: Huge bundles of subcortical fibers, like uncinate, inferior fronto-occipital and arcuate fascicles, connect the insula to the neighboring structures. Several anatomical structures related to neurological disabilities are closely related to insular surgery, like the middle cerebral artery, internal capsule, lenticulostriate arteries and cortical and subcortical language circuits. Conclusions: Microsurgical laboratory training, 3D documentation, knowledge of brain mapping and modern neurosurgical armamentarium are important factors in achieving good results with insular glioma tumors.

Purpose@#This study aimed to assess the feasibility of a rapid diffusion tensor imaging (DTI) for evaluation of the female urinary sphincter function based on differentiation between rest and muscle contraction. @*Methods@#Magnetic resonance imaging (MRI) of the lower pelvis was performed at 3 Tesla in 10 healthy female volunteers (21–36 years; body mass index, 20.8±3.6 kg/m2) between June and July 2019. High-resolution T1- and T2-weighted images were acquired for anatomical reference, and following DTI performed in 4 experiment phases: twice during rest (denoted rest-1, rest-2) and contraction (contraction-1, contraction-2). Manual segmentation of the urinary sphincter and the levator ani muscles were performed by 2 independent readers. Mean diffusivity (MD) and fractional anisotropy (FA) values derived from DTI volumes were compared in search for significant differences between the experiment phases. Interreader agreement was assessed by intraclass correlation coefficient (ICC). @*Results@#Kruskal-Wallis test showed significant differences between MD values among all the experiment phases, by both independent readers (1st: X2 [3,76]=17.16, P<0.001 and 2nd: X2 [3,76]=15.88, P<0.01). Post hoc analysis revealed differences in MD values by both readers between: rest-1 vs. contraction-1 (least P<0.05), rest-1 vs. contraction-2 (P<0.01), rest-2 vs. contraction-1 (P<0.03), rest-2 vs. contraction-2 (P=0.02) with overall mean ‘rest’ to ‘contraction’ ΔMD=20.6%. No MD or FA differences were found between rest-1 vs. rest-2 and contraction-1 vs. contraction-2 among all the experiment phases, and interreader agreement was ICC=0.85 (MD) and ICC=0.79 (FA). @*Conclusions@#Rapid DTI might prospectively act as a supporting tool for the evaluation of female pelvic floor muscle function, and incontinence assessment.

RESUMEN
Background There has been a push toward implementation of electronic health records (EHRs) in federally-funded hospitals under the current policies initiated by the Indian government, with a lack of evidence supporting their adoption. We analyzed data from the American College of Cardiology’s PINNACLE (Practice Innovation and Clinical Excellence) India Quality Improvement Program (PIQIP) to evaluate the association between EHR use and quality of cardiovascular disease care in India. Methods and Results Between 2011–2016, we collected data on performance measures for patients with coronary artery disease (CAD), heart failure (HF) and atrial fibrillation (AF) among 17 participating practices in PIQIP. There were 19,035 patients with CAD, 9,373 patients with HF, and 1,127 patients with AF. Documentation of co-morbidity burden in patients with CAD was lower among practices with EHR—hypertension (49.8% vs. 52.1%, p = 0.003), diabetes (34.9% vs. 38.3%, p < 0.001), and hyperlipidemia (0.2 vs. 3.9%, p < 0.001). On the contrary, documentation of medication prescription was higher in CAD patients seen at practices with EHR—aspirin (63.2% vs. 17.8%, p < 0.001), clopidogrel (41.7% vs. 27.4%, p < 0.001), beta-blockers (61.4% vs. 9.8%, p < 0.001), and ACE-i or ARBs (53.9% vs. 16.4%, p < 0.001). Similarly, documentation of receipt of beta-blockers (43.8% vs. 10.7%, p < 0.001), ACE-i or ARBs (40.8% vs. 16.1%, p < 0.001), and beta-blockers + ACE-i or ARBs (36.4% vs. 3.6%, p < 0.001) was also significantly higher in patients with HF seen at practices with EHR. Among patients with AF, documentation of oral anticoagulation use was significantly higher among EHR practices—warfarin (42.5% vs. 26.1%, p < 0.001). Conclusions Documentation of receipt of guideline-directed medical therapy in CAD, HF, and AF was significantly higher in practices with EHRs in India compared with sites without EHRs. Our findings shed a spotlight on the value of EHRs in future health care policy-making in India with regard to widespread adoption of EHRs in primary and advanced specialty care settings across public and private sectors.
RESUMEN
Context: Lymphomatoid granulomatosis (LYG) is a rare B-lymphoproliferative disorder characterised by an angiocentric and angiodestructive pattern along with Epstein - Barr virus (EBV) association. It is one of the diagnostic challenges in lymphoma pathology. Deregulation of EBV immune surveillance is one of the narrated hypotheses in the literature. Extrapulmonary manifestations are rare with LYG. Morphological grading is done based on the number of EBV-positive B cells, which is useful to strategize treatment protocol. Aims: We report here a series of nine cases of LYG to discuss the clinical, histological, and immunohistochemistry findings. Settings and Design: This is the first case series from India in published literature. Subjects and Methods: We reviewed cases of LYG diagnosed at our center for the past 11 years (2006-2016). A total of nine cases were included in this study. Histomorphology was studied in conjunction with immunohistochemistry and clinical details. Cases without classical morphology and negative for EBV immunostain were excluded from the study. Results: There were nine patients in our study (7 males and 2 female; M:F ratio 3.5:1). The age of these patients ranged from 4 years to 57 years (mean age: 30 years). The most common site involved was the lung (4, 44%), followed by the skin (2, 22%), central nervous system (2, 22%) and lymph node (1, 11%). One patient had primary immunodeficiency. Another patient had undergone renal transplant 11 years before the development of the lesion. Angiocentricity and angioinvasion were appreciated in all nine cases (9/9) with necrosis in four cases (44%) and ill-defined histiocytic aggregates in three cases (33%). The histological features were as follows: Grade 1(4 cases, 44%), Grade 2(2 cases, 22%), and Grade 3(3 cases, 33%). Conclusion: LYG is a rare EBV driven angiodestructive disease with predominantly lung involvement as well as isolated extrapulmonary sites as seen in our study. It is often progressive and ultimately fatal in the absence of appropriate treatment. Grading of the lesion helps to initiate the appropriate treatment of choice.
RESUMEN
ABSTRACT Objective To evaluate the role of the involvement of white matter tracts in huntingtin gene mutation patients as a potential biomarker of the progression of the disease. Methods We evaluated 34 participants (11 symptomatic huntingtin gene mutation, 12 presymptomatic huntingtin gene mutation, and 11 controls). We performed brain magnetic resonance imaging to assess white matter integrity using diffusion tensor imaging, with measurement of fractional anisotropy. Results We observed a significant decrease of fractional anisotropy in the cortical spinal tracts, corona radiate, corpus callosum, external capsule, thalamic radiations, superior and inferior longitudinal fasciculus, and inferior frontal-occipital fasciculus in the Huntington disease group compared to the control and presymptomatic groups. Reduction of fractional anisotropy is indicative of a degenerative process and axonal loss. There was no statistically significant difference between the presymptomatic and control groups. Conclusion White matter integrity is affected in huntingtin gene mutation symptomatic individuals, but other studies with larger samples are required to assess its usefulness in the progression of the neurodegenerative process.
RESUMO Objetivo Avaliar o envolvimento da substância branca (SB) cerebral em indivíduos com mutação do gene da huntingtina. Métodos Foram avaliados 34 indivíduos: 11 com mutação do gene da huntingtina sintomática, 12 assintomáticos com mutação do gene da huntingtina e 11 indivíduos controles. Realizamos ressonância magnética cerebral para avaliar a integridade da SB usando o tensor de difusão (DTI), com medição da anisotrofia fracionada (FA). Resultados Observamos uma diminuição da FA no trato corticoespinhal, coroa radiada, corpo caloso (joelho, corpo e esplênio), cápsula externa, radiações talâmicas, fascículo longitudinal superior e inferior, e fascículo frontal-occipital inferior no grupo dos indivíduos com mutação sintomática. A redução da FA é indicativa de processo degenerativo e perda axonal. Não houve diferença estatística entre os grupos controle e pré-sintomático. Conclusão Houve comprometimento da integridade da SB em indivíduos com mutação no gene da Huntingtina sintomática, mas outros estudos são necessários para avaliar a sua utilidade na progressão do processo neurodegenerativo.

ABSTRACT Trypanosomatid type I nitroreductases (NTRs), i.e., mitochondrial enzymes that metabolise nitroaromatic pro-drugs, are essential for parasite growth, infection, and survival. Here, a type I NTR of non-virulent protozoan Trypanosoma rangeli is described and compared to those of other trypanosomatids. The NTR gene was isolated from KP1(+) and KP1(-) strains, and its corresponding transcript and 5' untranslated region (5'UTR) were determined. Bioinformatics analyses and nitro-drug activation assays were also performed. The results indicated that the type I NTR gene is present in both KP1(-) and KP1(+) strains, with 98% identity. However, the predicted subcellular localisation of the protein differed among the strains (predicted as mitochondrial in the KP1(+) strain). Comparisons of the domains and 3D structures of the NTRs with those of orthologs demonstrated that the nitroreductase domain of T. rangeli NTR is conserved across all the strains, including the residues involved in the interaction with the FMN cofactor and in the tertiary structure characteristics of this oxidoreductase protein family. mRNA processing and expression were also observed. In addition, T. rangeli was shown to be sensitive to benznidazole and nifurtimox in a concentration-dependent manner. In summary, T. rangeli appears to have a newly discovered functional type I NTR.

Objective[s]: Lutetium-177 can be made with high specific activity and with no other isotopes of lutetium present, referred to as "No Carrier Added" [NCA] [177]Lu. We have radiolabelled DOTA-conjugated peptide DOTA-[Tyr[3]]-octreotate with NCA 177Lu ["NCA-LuTATE"] and used it in nearly 40 therapeutic administrations for subjects with neuroendocrine tumours or meningiomas. In this paper, we report on our initial studies on aspects of the biodistribution and dosimetry of NCA-LuTATE from gamma camera 2D whole body [WB] and quantitative 3D SPECT [qSPECT] [177]Lu imaging
Methods: Thirteen patients received 39 NCA-LuTATE injections. Extensive WB planar and qSPECT imaging was acquired at approximately 0.5, 4, 24 and 96 h to permit estimates of clearance and radiation dose estimation using MIRD-based methodology [OLINDA-EXM]
Results: The average amount of NCA-Lutate administered per cycle was 7839 +/- 520 MBq. Bi-exponential modelling of whole body clearance showed half lives for the fast and slow components of t[1/2]=2.1 +/- 0.6 h and t[1/2]=58.1 +/- 6.6 h respectively. The average effective dose to kidneys was 3.1 +/- 1.0 Gy per cycle. In eight patients completing all treatment cycles the average total dose to kidneys was 11.7 +/- 3.6 Gy
Conclusions: We have shown that NCA-LuTATE has an acceptable radiation safety profile and is a suitable alternative to Carrier-Added [177]Lu formulations. The fast component of the radiopharmaceutical clearance was closely correlated with baseline renal glomerular filtration rate, and this had an impact on radiation dose to the kidneys. In addition, it has less radioactive waste issues and requires less peptide per treatment
